我架了一台Debian主機在學校,但在校外卻無法登入。問過計中的人,他們說若可以上學校網站就表示線路OK。但現在我卻要透過某老師的Linux主機再用SSH登入到我自己的主機裡。但最近我重新安裝Debian在由老師主機登入我的主機時發現以下的問題:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
79:7b:7e:31:ba:05:db:9a:7e:f2:0b:e0:49:4a:0c:b5.
Please contact your system administrator.
Add correct host key in /home/dolphin/.ssh/known_hosts to get rid of this message.
Offending key in /home/dolphin/.ssh/known_hosts:1
RSA host key for 140.127.192.XX has changed and you have requested strict checking.
Host key verification failed.
想不出未何?~~!! 請各位先進指點~! Thanks~!
